Product description
With a rated torque of 7.3 Nm at 3000 min⁻¹, the Siemens 1FK7063-5AF71-1AA0 belongs to the compact SIMOTICS S 1FK7 servomotor series in shaft height 63. At this rated speed, the permanent-magnet synchronous motor provides 2.29 kW. Its stall torque at 100 K is 11 Nm, with a corresponding stall current of 8 A. The rated operating point is documented at 5.6 A; the mechanical limits are 7200 min⁻¹ and a maximum torque of 35 Nm. These values distinguish the continuous and limit ratings of winding version 5AF71. Feedback is provided by an incremental encoder with a sin/cos signal, 1 Vpp and 2048 signal periods per revolution. Power and signal connections use separate plug connectors that can be rotated through 270°. The motor shaft has a key and keyway with runout tolerance N. This AA0 version is configured without a holding brake. Its moment of inertia without brake is 15.1 × 10⁻⁴ kgm², while the torque constant is 1.37 Nm/A. A thermal time constant of 40 minutes complements the electrical and dynamic data. The motor uses natural cooling and is specified for mounting positions IM B5, IM V1 and IM V3. Its degree of protection is IP64. Shaft height 63 and the square 126 mm flange outline define the mechanical frame size. The shaft projects 50 mm beyond the flange and has a diameter of 24 mm. For the version with incremental encoder and without brake, the dimensional drawing indicates approximately 225 × 126 × 126 mm; additional connector space must be considered during installation planning. The documented motor weight without holding brake is 11.5 kg.
